The only two cars on this Forum running with this setup are and one of mine.

Based on the issues that haven't been sorted out yet, my advice would be to wait until we sort out the problems.

Moving to Performance and Brainstorming.

I can get pics of a 92 TB next to a 94 in the near future.

I had both sitting side-by-side not too long ago, but didn't snap a pic.

There'* a noticable difference. The 94/95 is closer in size to the Series 2 than it is the 92/93.

Great info, thanks

Who offers an AFC please?

Care to elaborate on the issues you have encountered, other than poor idle? If this discussion has already occured elsewhere, please point me to it.

Please don't rely on an AFC to solve all your problems. It'* not a long-term permanent solution, especially on a forced-inducted car.

Use it as a tuning method on the road to a custom PCM.

Ah, I have the 1.1 version. Seems now the 2.2 is fully functional. I'm not too impressed with the packaging, not very robust given the engine compartment environment...

Well, I seemed to have lucked out today and picked up a complete throttle body that originated a 95 SSEi'. All the PN'* (MAF, IAC, throttle body) jive with GM PN'*. It is significantly larger than the 92/93 version. This wrecker even had a M62 and an (1997) M90...

Damn you type a lot Oh and there are more than two running that setup (sig).

When I did the swap some time ago I spent a LOT of time with a dial caliper and scratch pad to note the differences. Oh and there were a-plenty! I took quite a few hours to do a simple 30min swap just because I wanted to note every difference I could find. I made a post some time back with my findings but a thicker housing was certainly one of them. You have one of each, right? Pull them out with a dial/digital caliper and have a look. You may not have noticed the injector seating because you almost have to be looking for it to tell, but it was enough of a difference to force me to readjust a few times and something to watch for.


As for the swap itself...Not a problem. I did make a small adjustment to the AFC but really just bolt-on and go! I'm not sure why you dislike the afc so much, aside from a couple hundred dollars for a custom PCM and dyno tuning it'* really a decent solution. I've been running it for quite a while not and never had a problem with it. I am, however, well aware of its shortcomings and will be the first to say it'* not a perfect solution for everyone, but it works.

JMO here, careful to read forward...I think there really should be a shift in the mindset of some of the performance enthusiasts here. It seems anytime ONE person does something with X effect it suddenly becomes the known-fact-absolute when later referenced. On several occasions I've had to come behind and argue to the opposite and bit by bit have worked to squash some long held misbeliefs. It can be seen from some of my earliest posts and carries on today. I'm still trying to get you to change the Tech-Info about the NA/SC swap. I personally know three people now that have done it..yes, it'* possible. But some time ago someone had the thought that it wouldn't be possible and it has stuck ever since. I think there should be a huge gap between "I wouldn't do it" and "You can't do it."

One thing I'm not sure many people realize here, the S1 performance community is MUCH MUCH MUCH larger than what'* held within this club. Until I started SOP I thought I had seen it all, NO WAY! There are some absolutely insane S1'* with setups that are "impossible" and driving fine. You know there'* a twin-charged S1 running around out there? You know there'* a twin-turbo S1 out there? I even saw the beginning of an M90 swap. Surely climbing an upside down ladder, but interesting that someone would look at it seriously.

I know I'm not around as much as I used to be, maybe I should be. At least to post about the interesting stuff that'* out there. For example, right now I'm swapping emails with a guy that has a 1991 engine....supercharged....'57 Drag Cam...In a Sunbird. Tie all that together.

Damn I type a lot.
